This tent reminds me of the Kelty Whitecloud released about a 15 yrs ago.
A mainstream gear manufacturer decides to REALLY get on the ultralight bandwagon and release an uber-light (1 lb for an ~5000 ci pack), very durable, iconic looking and expensive piece of gear.

$500 in 2000 money...or about $650 today.
This tent, however, takes the cake.
As an aside, Kelty and Sierra Designs are owned by the same company. Hmmm...
(And this type of gear is why I call myself a minimalist and not an ultra-lighter. :O )
